摘要
针对胶球清洗凝汽器结垢容易丢球、毁球等问题,研制出一种能够自动检测胶球数量及其半径的自动监测装置。首先,对顺序采集的胶球图像进行图像拼接,去除重复部分;然后采用灰度变换、图像平滑等一系列预处理算法去噪,去噪后结合基于最小误差分割法的灰度图二值化变换对图像进行分割,得到目标明确的分割图像;最后,利用二值图像投影变换,进行胶球位置定位,获得胶球的数量及磨损状况。多次试验结果表明,算法具有很好的实时性和有效性。
Aimed at the problem that balls easily lost or shatter when cleaning the condenser,an automatic monitor which can automatically check the quantity and quality of the circulating balls is developed.First,to get rid of the repeated part between ordinal border upon images,image joint algorithm is adopted,and then,use a series of pretreating methods,such as gray transformation and image smoothing,to take off the yawp,segment the image with gray image binary transformation based on the minimum error method,by this,the segmented image with clear target is got.Finally,through binary image projection transformation,ball's position is achieved,one by one,the quantity and quality of the cleaning ball is obtained.Experiment proves good real time performance and efficiency of this recognition algorithm.This device serves as an optional add-on part to the condenser cleaning system.
